ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

NWMO chooses vendors for Canadian repository
Canada’s Nuclear Waste Management Organization has selected five companies it is to work with to design and plan the organization’s proposed deep geologic repository for spent nuclear fuel. As the owner of the project, the NWMO will be working with WSP Canada, Peter Kiewit Sons (Kiewit), Hatch Ltd., Thyssen Mining Construction of Canada, and Kinectrics.
Educational Session|Panel|Sponsored by Plant Reliability
Monday, August 5, 2024|3:30–5:00PM EDT|Banyan 2
The increasing trend in extreme weather events disrupting the electric grid has resulted in environmental resiliency becoming a focal point for energy providers and regulatory agencies. To this effect, INPO recently release a principles document, INPO 24-003 (Resiliency – Strengthening Defenses Against External Forces) and a Tier 2 guidance document specifically associated with assessing climate vulnerabilities, INPO 24-002 (Climate Vulnerability Assessment).
This session will provide perspective on these INPO documents and discuss next steps for utilities to ensure environmental resiliency. The session will also address a specific challenge one utility is facing due to the changes in the local environment, which is directly affecting the supply of cooling water to the station. Finally, the session will discuss challenges in the management of the seasonal readiness process and potential impacts on plant reliability.
